From: Arnd Bergmann <arnd@arndb.de>

kaslr_early_init() is called from assembler code and does not
need a declaration to work, but adding one anyway shuts up
this W=1 warning:

arch/arm64/kernel/pi/kaslr_early.c:88:16: error: no previous prototype for 'kaslr_early_init' [-Werror=missing-prototypes]
